    专利说明:

    The present invention relates to the field of home automation and / or building automation for residential, commercial or industrial use. The invention relates more particularly to a radiofrequency device for a home automation or building automation system for concealment or protection for an opening and an associated home automation installation.
    Thereafter the term “home automation” will be used to designate the concepts of home automation and building automation. In general, the term “home automation” will designate all of the electronics, building physics, automation, IT and telecommunications techniques used in commercial, industrial or residential buildings, which they are individual or collective.
    In general, the present invention relates to the field of domotic, blackout, sun protection, closure and / or protection installations for an opening in a building.
    Such installations may include a radiofrequency transmission and / or reception device. The radiofrequency device comprises at least one radiofrequency antenna in order to increase its sensitivity and therefore the range of the transmission between the transmitter, respectively the receiver, of the radiofrequency device and the receiver, respectively the transmitter, of a remote device.
    In certain embodiments, for example in the case of a rolling shutter, the radiofrequency device is generally placed in a metal casing, which makes it necessary to move the antenna (s) outside this metallic casing to preserve sensitivity. However, this solution is not very aesthetic because the antenna becomes visible.
    This solution also requires piercing the metal casing, which affects, for example, its sealing. The antenna is generally wired, so an installer who sees an unconnected wire may think that this wire is not used and may be tempted to cut it in order to improve the aesthetics of the installation.
    When the radiofrequency device is used in a protective device for opening, such as a sensor or a detector, the same aesthetic problem arises. For example, opening detectors are generally mounted on doors or windows, which detracts from their appearance. In addition, these devices are easily located by a malicious person who can destroy it to neutralize it.
    In this context, it is interesting to propose a solution which makes it possible to camouflage the antenna of the radiofrequency device without modifying the radiofrequency performance thereof.
    There are known embodiments in which the antenna, generally wired, is hidden in the frame of a door or a window. However, this solution is not perfect because the upright material, generally polyvinyl chloride (also known as PVC for "PolyVinyl Chloride) modifies the technical characteristics of the antenna and in particular reduces its range. The degradation of the antenna performance is accentuated when the polyvinyl chloride is loaded with metallic particles, for example, to reinforce its solidity. In addition, when the amount in which the antenna is placed is metallic, for example, aluminum, the range of the antenna is very greatly reduced, see canceled.
    An object of the invention is in particular to correct all or part of the aforementioned drawbacks by proposing a radiofrequency device comprising a discrete antenna and the performance of which is not degraded following the mounting of the radiofrequency device in a domotic or protective home installation.
    This object is achieved by the use of a planar antenna in a concealment installation, a closing home automation installation or a protective home automation installation and more particularly in the radiofrequency device of these home automation installations.
    To this end, the subject of the invention is a radiofrequency device intended to be mounted in a domotic installation for closing, concealing or protecting an opening, the opening comprising an opening and a frame surrounding the opening, the device comprising an antenna of the planar type fixed on a part of the opening leaf or of the opening frame or on a guide rail of the installation or on a trunk of the installation or on a load bar of installation. In other words, the planar antenna is intended to be mounted on the sash or on the frame or on a guide rail of the installation or on a trunk of the installation or on a load bar of the installation.
    According to an alternative embodiment, the part on which the antenna is fixed is metallic.
    According to an alternative embodiment, the device comprises a coaxial connection for feeding the antenna.
    According to an alternative embodiment, the device comprises a microstrip line for feeding the antenna.
    According to an alternative embodiment, the device comprises a radome surrounding at least part of the antenna.
    Another object of the invention is a home automation element comprising a member of the opening or sleeping type or guide slide of a screen or home automation installation box or home automation installation load bar and an antenna of the planar type, the antenna being fixed on the organ or on a part of the organ.
    The invention also relates to a domotic installation for concealing, closing or protecting an opening comprising a radiofrequency device as described above and / or a home automation element as described above.
    The subject of the invention is also a method of mounting a radiofrequency device for a domotic installation for concealing, closing or protecting an opening comprising the following steps:
    - provide a planar type antenna, and
    - fix the antenna on a part of a window or a frame or a guide rail of a screen or of an installation chest or a load bar of the installation.
    According to one embodiment, the method comprises a step of drilling the part on which the antenna is fixed.
    Other particularities and advantages of the present invention will appear more clearly on reading the description below, given by way of illustration and not limitation, and made with reference to the appended drawings, in which:
    FIG. 1 represents an exemplary embodiment of a domotic occultation installation;
    FIG. 2 represents an exemplary embodiment of a planar antenna supplied by line;
    FIG. 3 represents a sectional view of a planar antenna supplied by coaxial link.
    The invention relates to a radiofrequency device for a domotic installation for concealing or protecting an opening in a building.
    FIG. 1 represents an exemplary embodiment of a domotizing domotic installation 3 intended to be installed in a building comprising an opening, such as a window or a door. The opening comprises an opening, such as a leaf, and a frame, such as a frame surrounding the opening and on which the opening is movably mounted. The opening is equipped with a screen 2, that is to say that a screen of the home automation installation is arranged at the level of the opening for example to cover and / or close and / or conceal and / or protect the opening.
    A domotization home automation installation 3 comprises a motorized drive device 5 which sets in motion a screen 2, between at least a first position and at least a second position. The motorized drive device 5 comprises an electromechanical actuator 11 of a movable element for closing, concealing and / or sun protection such as a rolling shutter, a shutter, a door, a grid, a canvas blind. or with adjustable slats or any other equivalent material, hereinafter called screen 2. The domotizing home automation installation 3 may however also be a garage door or a motorized gate.
    The electromechanical actuator 11 comprises an electric motor, an output shaft and an electronic control unit 15 in a known manner. In particular, the electromechanical actuator 11 may be a tubular actuator, intended to be inserted in a winding tube 4 on which the screen 2 is wound.
    According to another embodiment, not shown, the home automation installation can be a device for protecting an opening intended for the security of a building. It may be a sensor, a detector, in particular an opening detector, an anti-intrusion device, an anti-intrusion device or any other similar device capable of protecting a building opening such as a door or window. It can be a home automation protection system comprising one or more of the previously mentioned devices and an alarm center configured to communicate with these protection devices.
    The closing, concealing or domotic protection home automation installation further comprises a radiofrequency device 12 configured to receive and / or transmit radiofrequency signals from and / or to another remote radiofrequency device 13 according to a communication protocol. The radiofrequency device 12 notably comprises a power supply device, a high frequency amplifier-demodulator circuit, one or more microcontrollers or processors or any other equivalent means programmed in a timely manner as well as any element known to those skilled in the art. Therefore, the radiofrequency device is able to receive, decode signals representative of control commands or information and / or transmit signals representative of control commands or information.
    By way of nonlimiting example, the radiofrequency device 12 can be able to transmit and / or receive radiofrequency signals on frequencies substantially equal to 433MHz, 868 MHz or 2.4 GHz.
    The radio frequency device 12 can be arranged to receive radio signals from another remote radio frequency device 13. It can be, for example, a remote control device issuing instructions for piloting the home automation installation and / or control orders and / or information.
    The radio frequency device 12 can be a transmitter module configured to transmit radio signals to another remote device. The radiofrequency device 12 can, for example, send reports on the operating state of the home automation system for diagnostic purposes and / or radio frequency signals relating to one or more states of the domotic or concealing home installation. protection. In the case of a protection system, the radio frequency device 12 can be configured to send control orders and / or alert messages to an alarm center following an opening detection, an attempt burglary or any other event relating to the security of the door or window.
    According to an alternative embodiment, the radiofrequency device can combine the two previously mentioned embodiments. It can be a transmission / reception module designed to communicate bidirectionally with a remote device. In the case of a concealment installation, it may be a remote weather station outside the building, including one or more sensors which can be configured to determine, for example, a temperature, a brightness, or another wind speed. When the home automation installation is intended for the security of a building opening, the remote radio frequency device can for example be an alarm center.
    In general, the remote radiofrequency device 13 can be, for example, a remote control, a smart phone (or smartphone according to English terminology), a touch pad, a multiservice unit (or box according to English terminology), a alarm center or any other equivalent device. It can be a nomadic or fixed radiofrequency transmitter and / or receiver. The remote radio frequency device 13 can be configured to allow a user to adjust parameters of the home automation installation and / or to control it.
    The radiofrequency device 13 of the home automation installation comprises a radiofrequency antenna 20. In order to reduce the size of the antenna (surface and height) and therefore its visual impact, the antenna is chosen to be of the planar antenna type. The antenna can be a printed radiating element antenna, generally called a "patch antenna". It can also be an F-type antenna.
    Referring to Figure 2, a printed antenna 20 includes a radiating element 21 formed by a conductive surface of predetermined geometric shape. The radiating element 21 can have different geometric shapes such as for example a square or rectangle. The size of the radiating element 21 conditions the resonant frequency of the antenna 20. One of the dimensions of the radiating element is substantially equal to a quarter of the wavelength associated with the resonant frequency of the antenna. The radiating element is deposited on one face of a dielectric substrate 22. The other face of the dielectric substrate is completely or partially covered with a conductor, for example metallized in order to form the ground plane 23 of the antenna. Advantageously, this type of antenna has a small thickness. Its thickness h corresponds to the thickness of the substrate which is generally between approximately 0.5 mm and 2.5 mm. Typically, its thickness is substantially equal to 1 mm.
    In order to reduce its surface area, the antenna 20 of the radiofrequency device can be produced from a dielectric substrate 22 having a high dielectric constant. By way of nonlimiting example, the dielectric used can be Polytetrafluoroethylene loaded with ceramic, sold under the brand DUROID®, whose relative dielectric permittivity is substantially equal to 10. Advantageously, the use of a substrate having a high dielectric permittivity makes it possible to significantly reduce the size of the antenna. Indeed, the size of the antenna 20 is inversely proportional to the square of the dielectric constant of the substrate used to form the antenna. This makes it possible to position the antenna 20, for example, on a frame or the frame of a window or a door such as a glass door which generally have a fairly small width, typically less than 10 cm.
    The planar antenna 20 can be supplied in different ways. According to one embodiment, the antenna is supplied by a microstrip line 24 connecting one side of the radiating element 21, as illustrated in FIG. 2. The microstrip line 24 may include a connector (not shown) on the non-end connected to the radiating element in order to connect it to the radiofrequency device 12 directly or via a cable, preferably coaxial, a first cable conductor being connected to the ground plane 23 of the antenna and a second cable conductor being connected to the microstrip line.
    According to another preferred embodiment, the planar antenna 20 is supplied by a coaxial link 31 or coaxial probe, as illustrated in FIG. 3. The external conductor of the coaxial link is connected to the ground plane 23 of the antenna and its central element to the radiating element 21 at a point allowing the adaptation of the antenna 20. The coaxial link 32 can comprise a connector 31 in order to connect it to the radiofrequency device 12. The connector 31 can, for example, be of the SMA type for SubMiniature version A. According to a preferred embodiment, the coaxial feed link of the antenna can be reduced to a connector 31, for example of SMA type whose central core is connected to the radiating element 21 .
    Unlike line supply, the antenna is supplied by coaxial probe from the part of the antenna comprising the ground plane, therefore the face opposite to that on which the radiating element 21 is printed. fact, this type of power does not change the surface occupied by the antenna and allows greater discretion of the latter.
    In order to increase the discretion of the antenna 20 and / or to protect it, the planar antenna may include a radome. The radome can cover at least a visible part of the antenna. It is formed using a non-magnetic material so as not to disturb the radiation from the antenna. Preferably, it is thin, for example in the form of a film. It can consist of one or more layers of paint of color substantially identical to that of the part on which the antenna 20 is fixed. According to an alternative embodiment, the visible part of the antenna can be covered with a tinted non-magnetic material forming the radome.
    The antenna can be fixed by gluing, from its ground plane, using glue or double-sided adhesive on the window frame or the opening of a window or door. According to an alternative embodiment, the antenna can be fixed by means of slides arranged to press its ground plane on a door or a window (dormant or opening). In the case of use with a rolling shutter, the antenna can be fixed on a guide rail 6 or on the trunk 9 of the rolling shutter. When the closing or blackout home automation system is a awning, the radio frequency antenna 20 can be fixed on the load bar of the installation. The antenna can still be attached in any other way. By "fix" is meant here preferably the making of a complete mechanical connection or a mechanical connection between the antenna and the element on which the antenna is fixed or of a mechanical connection such as a or several degrees of freedom of limited amplitude remain between the antenna and the element on which the antenna is fixed.
    In the case of attachment of the antenna to a mobile element, in particular to an opening, the cable connecting the antenna to the rest of the radiofrequency device is arranged so that the maneuvers or movements of the mobile element can be carried out without altering the electrical connection between the antenna and the rest of the radio frequency device.
    The antenna being fixed by its face containing the ground plane, the material (wood, PVC, metal ...) of the opening or a frame 6 on which the antenna is stuck does not degrade its radioelectric performance and therefore does not not degrade the performance of the radio frequency device 12.
    Advantageously, the attachment of the antenna to a leaf or a metal frame makes it possible to improve the radioelectric performance of the antenna as well as its range. Indeed, the metal part on which the antenna is fixed makes it possible to enlarge the ground plane of the antenna.
    Another object of the invention is a home automation element comprising a member of the opening or sleeping type or guide slide 6 of a screen 2 or box 9 of home automation installation or home automation installation load bar and an antenna of planar type , the antenna being fixed on the member or on a part of the member.
    The invention also relates to a domotic closing installation or a protective domotic installation for an opening comprising a radiofrequency device 12 as described above.
    The invention also relates to a method of mounting a radiofrequency device for a domotic closing or protective installation for an opening. The method may include a step of supplying a radiofrequency antenna 20 of planar type such as an antenna with a printed radiating element or of type F. The antenna 20 is then fixed to a part of the opening or of the frame of the opening. . The antenna can also be fixed on a guide rail of a screen or on a box 9 of the home automation installation or on a load bar of the installation.
    According to an embodiment, a step of drilling the part on which the antenna is fixed may be necessary, for example, in order to pass the feed link between the antenna 20 and the rest of the radiofrequency device 15 This supply link can be a cable, preferably coaxial, connecting the antenna 20 and the rest of the radiofrequency device 15. The drilling can be intended to allow the connector 31 fixed on the antenna 20 to pass through the part on which is attached the antenna.
